STS-48/STS-12/STS-3 Section Parameters 9
The following STS-48, STS-12 and STS-3 section parameters are monitored:
■ Section (B1) Coding Violations (CV-S): To monitor the performance of an
STS-48, STS-12 or STS-3 section, the section B1 parity is calculated,
written, and checked for errors. The section B1 parity violation counter is
incremented for each section error detected.
■ Section (B1) Errored Seconds (ES-S): An errored second (ES) is a
second in which there are one or more B1 parity violations detected, one or
more LOS defects, or one or more LOF defects.
■ Section (B1) Severely Errored Seconds (SES-S): A severely errored
second (SES) is a second in which there are 249 or more B1 parity
violations detected, one or more LOS defects, or one or more LOF defects.
■ Section (B1) Severely Errored Frame Seconds (SEFS-S): A section
severely errored frame second (SEFS) is the number of seconds during
which an out-of-frame event occurred.
A threshold crossing alert (TCA) is generated if an STS-48 or STS-3 section
parameter exceeds the provisionable threshold. The generation of TCAs can be
enabled or disabled using the PERFORMANCE-Set-PM Threshold-Section
input.
